In one of the A2 tests, I see « Il faut toujours regarder devant soi. » and « Il faut toujours essayer soi-même avant de juger. » When do you use soi vs soi-même? I keep getting docked for choosing soi-même in the first sentence.

Sometimes Vouloir (to want) is conjugated as veux at the present tense, but sometimes it is conjugated as veux for the pronoun je. Does this have to do with formality?

In the sentence: Tu ne peux rien mettre dans ce placard.   Why is rien before mettre and not after?

In Conte de fées (Passé Composé vs Imparfait) we're given the clue so his daughter had to take care of the garden and the animals. with 'devait' given as the correct answer and not 'a dû'. Why is that the case, when in this class it seems to be the opposite way around? It follows the context of her father rarely leaving his bed, and is followed by describing something she would also do once a month. So it seems unlikely to fit the 'we don't know if she fulfilled that obligation' case for using devait.
